This experiment was performed in order to study the effects of haepyoyijintang on the injured tracheal tissue induced $SO_{2}$ in rats. Healthy adult male rats weighting about 250g were divided into 4 groups-the Normal group, the Control group, the group of Haepyoyijintang administration for 5days after $SO_{2}$gas exposure (Sample I), and the group of Haepyoyijintang adiministration for 10 days before and for 5days after $SO_{2}$ gas exposure (Sample II). The results were obtained as follows; 1. In the trachea Control group, the lesion of the ciliated epithelium was and the mucus secretion of the respiratory tract was increased iginificantly. 2. In the trachea of SampleIgroup, the lesion of the ciliated epithelium and the mucus secretion of the respiratory tract were decreased compared with Control group. 3. In the trachea of SampleIIgroup, the lesion of the ciliated epithelium and the mucus secretion of the respiratory tract were decreased compared with Control and Sample Igroup. According to the above results, Haepyoyijintang has significant effects on the injuried tracheal tissu caused by $SO_{2}$ in rats.

This experiment was performed in order to study the effects of Haepyoyijintang on the pulmonary injury caused by $SO_2$. Healthy adult male rats weighting about 250g were divided into 4 groups- the Normal group, the Control group, the group of Haepyoyijintang administration for 5 days after $SO_2$ gas exposure (Sample I ), and the group of Haepyoyijintang administration for 10 days before and for 5 days after $SO_2$ gas exposure (SampleⅡ). The results were obtained as follows; 1. In the total number of leucocyte, Sample I and Sample II decreased significantly compared with Control group. 2. In the erythrocyte sedimentation rate, Sample I and Sample Ⅱ decreased significantly compared with Control group. 3. In the lung weight, Sample I and Sample II decreased significantly compared with Control group. 4. In the lung TBA level, only Sample II decreased significantly compared with Control group. 5. In the tracheal glycoprotein level, Sample I and Sample II decreased significantly compared with Control group. According to the above results, Haepyoyijintang has significant effects on the pulmonary injury caused by $SO_2$ in rats.
